Double poling is a cross country skiing technique that requires power, skill and timing. The purpose of this game is to double pole as far as possible in 60 seconds.
You double pole while holding your iPhone like a ski pole. The built in accelerometer in your iPhone detects power, pace and movement and calculates the distance.
If you have an iPhone 4S you can view your performance during your run using AirPlay mirroring and an Apple TV.
